The usefulness of the Hounsfield unit and stone heterogeneity variation in predicting the shockwave lithotripsy outcome.

Diagn Interv Radiol 2022 May;28(3):187-192

Department of Urology, Adıyaman University Education and Research Hospital, Adıyaman, Turkey.

PURPOSE This study aimed to evaluate the use of stone density variation coefficient (SDVC) as an indicator of stone heterogeneity and previously reported parameters for predicting extracorporeal shock wave lithotripsy (ESWL) outcome in urinary calculi. Moreover, a new formula that could be used to predict ESWL success was suggested. METHODS A total of 850 patients, who underwent the first session of ESWL for urinary stones between 2015 and 2020, were examined, and 220 eligible patients were included in the study. Read More

Endoscopic Management of Complex Biliary Stones.

Gastrointest Endosc Clin N Am 2022 Jul 11;32(3):477-492. Epub 2022 May 11.

Department of Gastroenterology, Hepatopancreatology, and Digestive Oncology, CUB Hôpital Erasme, Université Libre de Bruxelles, Route de Lennik 808, Brussels 1070, Belgium.

Complex biliary stones may be challenging to remove with standard endoscopic techniques. Factors contributing to complexity include large stone size (≥15 mm), multiple stones, high stone:distal duct ratio, stones above strictures and those in difficult anatomic position. In these cases, additional techniques may be needed, such as endoscopic papillary large balloon dilatation, mechanical lithotripsy, cholangioscopic visually directed lithotripsy, and extracorporeal shockwave lithotripsy.

Investig Clin Urol 2022 May 16. Epub 2022 May 16.

Department of Urology, Seoul National University College of Medicine, Seoul, Korea.

This article aimed to review the clinical application and evidence of the therapeutic ultrasound in detail for urological diseases such as prostate cancer, kidney tumor, erectile dysfunction, and urolithiasis. We searched for articles about high-intensity focused ultrasound (HIFU), extracorporeal shock wave therapy, ultrasound lithotripsy, and extracorporeal shockwave lithotripsy (ESWL) in the MEDLINE and Embase. HIFU may be indicated as a primary treatment for low- or intermediate-risk prostate cancer, and salvage therapy for local recurrence as a promising way to address the limitations of current standard therapies.

J Pak Med Assoc 2021 Oct;71(10):2407-2414

Sindh Institute of Urology and Transplantation (SIUT), Karachi, Pakistan.

There is very little published literature on urologic diseases prior to 1947 from areas now constituting Pakistan. From inception of the country to 1970s, urology was part of surgery practiced by general surgeons except for two urology units established in 1960s. The real take off of urology began with introduction of transurethral resection of prostate (TURP) in 1980s, ushering the era of endourology; the second era of which began with ureteroscopy along with extracorporeal shockwave lithotripsy (ESWL) in 1987-1989, percutaneous nephrolithotomy in 1992 and introduction of percutaneous nephrostomy in 1997.
